.Application filed May 6, 1922. Serial No, 558,942.

useful Loom Attachment, of which the following is a specification.

This invention alms to provide novel means whereby, when theharness strap of a loom breaks, and when the harness frame` drops, the loom will'be stopped.

It is within the `provinceof the disclosure to improve generally and to enhance the utility of devices of that type to which the invention appertains". f

Although a preferred embodiment of the invention is shown in the drawings, it will be understood that that embodiment is inserted for the sake of illustration, merely, and that a mechanic, working within the scope of what is claimed, may make such alterations as his skill and judgment may dictate, without departing from thespirit of the invention or avoiding the charge of infringement.

In the drawings Figure 1 shows in perspective, a device constructed in accordance with the invention, the same being mounted on a portion of a loom, shown in dotted line; Figure 2 is an elevation showing a portion of a loom,

' the attachment claimed being mounted thereon, parts appearing in section; Figure 3 is a section on the line 3 3 of Figure 2; Figure 4 is a section on the line 4 4 of Figure 1.

The numeral 1 marks the frame of a loom including a brace 2. The feeler 4 is carried by a shaft 5, supported for rocking movement, as indicated at 6, the feeler oscillating with respect to bars 3. The harness frame appears at 16, and the crank shaft at 28-all as understood readily by those familiar with the primary structural parts of a loom.

In carrying out the invention, bearings 7 are mounted at 8, for adjustment, on the frame 1, and in the bearings, a shaft 9 is supported for rocking movement. The shaft 9 is adjustable longitudinally in the bearings 7 but is held against longitudinal movement therein, through the instrumentalitv of collars 20, which, being secured adjustably at 21', to the shaft, coact with the bearings T to prevent the shaft nig endwise.

from ,mov-

At one end, the shaft 9 is suppliedwith an upstanding rst arm 10, having'an inwardly prolonged-extension 11, including a short depending finger 12. The finger 12 isiso lof' cated that, when the shaft 9 is rocked, the finger will enter between the bars 3 and in# trude into the path of the oscillatory feeler 4,`the movement of the feeler being arrested, suitable intermediate ydevices (not shown) operating to stop' thefloom, generally by re-` leasing the shipper from its 'holding notch, this, however. being a detail in the construc-t tion of the loom, and having no especial bearing on the device which forms the subject matter of this application.

A means is provided whereby the linger 12 normally is held out of the path of the feeler 4, and with this end in view, the shaft 9 respends to the action of a retractile spring 23, to dispose the `parts in the'position depicted in Figure 2, one end of the spring being secured at 25 to the frame 1, and the other end of the spring being secured to the shaft 9, eccentrically of the shaft. It may be expedient to attach the lower end of the spring 23 to a stop r22 on the shaft 9, as denoted by the numeral 24, the stop being adapted to engage the frame 1, as shown in Figure 4, and to limit the rotation of the shaft 9, responsive to the action of the spring 23.

When the shaft 9 rocks,y to interpose the finger 12 in thepath of the feeler 4, some means should be provided for limiting the rotation of the shafty 9 and, consequently, fixing the position of the finger 12 with respect to the feeler. Having this consideration in mind, the arm 10 on the shaft 9 is mounted somewhat loosely in an eye 14 forming part of a latch 15.` mounted to reciprocate in an opening 17 fashioned in the brace 2, the latch having a shoulder 18 and being provided with a projection 19, spaced from the shoulder. It is clear that when the arm 10 swings from the `solid line position of Figure 2 to the dotted line position of that figure (to enable the finger 12 to stop arm 10. HavinV advanced from the solid line position of *igure 2, to the dotted line position therein delineated, the arm 10 cannot swing backwardly to the solid line position, because the shoulder 18 will engage with the brace 2. An operator, however, may move the latch and disengage the shoulder 18 from the brace 2, whereupon the spring 23 Will react, the stop 22 cooperating with the frame, and the parts being restored to the positions shown in solid line in Figure 2.

It is contemplated that the loom shall stop, when the harness strap breaks, and

" when the harness frame 16 drops. In order that this operation ma)7 take place, the

`shaft 9 is supplied with asecond arm 26,

disposed at an angle to the first arm 10, and comprising an extension 27, located approximately parallel to the shaft 9 and extended beneath one end of the. harness `frame 16. Obviously, when the harness frame 16 drops, they shaft 9 will be rotated7 and the finger 12 will be interposed in the path of the teeler 25 4, as and for the purpose hereinbefore speci- Having thus described the invention, what is claimed is The combination with the harness and the feeler of a loom, of a movable member including an actuating part disposed in the path of the harness when the harness drops, and a stopping part movable into the path or' the feeler When said member is actuated by the dropping of the harness; spring means for operating said member, thereby to retract the stopping part with respect to the feeler; means for limiting the movement of said member responsive to the spring means; and a combined means 'for'limiting the movement of the stopping part toward the feeler and for holding the stopping part in operative relation to the teeler, said combined means being releasably under the control of Y an operator.

In testimony that I claim the foregoing as my own, I have hereto affixed my signature in the presence of two Witnesses.
